The company intends to continue to build and ship current model EPA-compliant trucks in all vehicle classes using appropriate combinations of earned emissions credits and/or non-compliance penalties (NCPs) during the transition to ICT+.

"We've shared our new technology path with the EPA and California Air Resources Board (CARB), and both agencies are encouraged by our plans," Ustian said. "We will continue to work with the agencies to ensure that our customers receive uninterrupted deliveries in all 50 states during this transition."
